Why don't solar eclipses occur every time the moon is positioned between the sun and the earth?

Well, honey, if the moon had its way, we'd be having solar eclipses all the time! But let me tell you, it's all about that pesky tilt of the moon's orbit. If it played nice and aligned perfectly with the Earth's orbit around the sun, we'd have regular eclipses on the menu. But alas, life loves throwing a curveball or two.
